These files are created by taking the outgoing rotation group from each month of the Current Population Survey (CPS). The end result is a large yearly file of the basic CPS questions (employment status, occupation, income, marital status, etc.). The main virtue of this file is that is has roughly three times as many observations as the widely used March CPS. Another advantage is that the usual weekly data have current pay and current characteristics whereas the March survey links last year's earnings to current characteristics. Include general paragraph describing outgoing rotation files. This version of the data are from UNICON [www.unicon.com]. UNICON provides uniform variable naming across all survey years, has an interface that allows easy extraction of selected variables across years. The extracts are either in ASCII or Stata and include code to make SAS or SPSS files.
